<P>I forgot to tell you. I am runing 3 blade prop (15.75-13 re-piched to 11) in a Focus I. It has been the best plane - prop combination for me. I know tha Bob Pastorello has been using 3 and 4 blade props. I am sure that he will see these e-mails and give you some more advice.</P>
<P>Good luck,</P>

<DIV><SPAN class=494073914-06082004><FONT face=Arial color=#0000ff size=2>I have a Focus II coming and need to order an engine. Does anyone know where I can find one? I understand that the retailers are out of stock. Also, of the various props, 17X12, 16X14, 3 bladed, etc., which one gives the best downline braking? Last question is about the header options, what are the costs and sizes of the various ones on the market. When I ran the OS 140 in 1997 I used a Mac header with an extension tube and a MAC tuned piped But if I recall correctly it was a .20 size pipe to simply act as a muffler. I detuned the engine so that it turned an APC 16X13N at 8100. Even that was a bit fast for the plane, a Steve Stricker Excalibur II, which was a big plane at the time. All help is appreciated. </FONT></SPAN></DIV>
